The MB Frames and Deceuninck partnership gives installers access to a broad range of high-quality PVCu windows and doors backed by experienced manufacturing and dedicated trade support. From our Bristol facility, we manufacture Deceuninck systems for trade professionals working across the West Country and beyond.
With more than 30 years of fenestration experience, MB Frames has grown to become the largest manufacturer of Deceuninck PVCu in the West Country. For installers, that scale means access to established window and door systems, plus the manufacturing capacity, product choice, and support needed to keep projects moving.
Why Does MB Frames Work With Deceuninck?
Deceuninck gives MB Frames access to a versatile PVCu system range that meets the requirements of different properties and customer preferences. For installers, that means greater flexibility when quoting replacement windows, renovations and larger residential projects.
Our PVCu range includes products such as the Classic 2500 Series, Encore 2800 Series, and flush sash windows, offering options from traditional chamfered profiles to sculptured and flush designs. This breadth of choice allows trade customers to offer homeowners solutions for both contemporary and traditional properties without compromising modern performance.
A Large-Scale Deceuninck Manufacturer in the West Country
At MB Frames, we combine Deceuninck systems with established manufacturing expertise at our 32,000 sq. ft facility in Bristol. Our production capacity allows us to manufacture up to 1,000 PVCu and aluminium products per week, supporting installers who need a dependable supply partner for projects of different sizes.
Scale alone is not enough, however. We emphasise consistent quality control throughout the process, from quotation through to despatch. Trade products can arrive stripped, cleaned and prepared, with relevant hardware and add-ons fitted before delivery, helping installers reduce preparation work on site.
For busy glazing businesses, dependable manufacturing and efficient product preparation can make day-to-day project management considerably simpler.
Deceuninck Products Designed Around Customer Demand
Modern customers expect new windows to offer more than attractive frames. Energy efficiency, security, low maintenance and design flexibility are all important considerations when homeowners choose replacement glazing. Deceuninck PVCu systems give MB Frames installers access to products designed around these requirements. Depending on the chosen range and specification, options include energy-efficient glazing, secure hardware and extensive colour and finish choices.
Deceuninck’s Heritage ranges also give installers options for projects where traditional appearance matters. This combination of performance and appearance gives installers a versatile range to present to customers across different project types.
